Moderate inverse
A real but noisy link — useful as context, risky as a standalone signal.
Dallas-based Texas Instruments generates over 95% of its revenue from semiconductors and the remainder from its well-known calculators. Texas Instruments is the world's largest maker of analog chips, which are used to process real-world signals such as sound and power. Texas Instruments also has a leading market share position in processors and microcontrollers used in a wide variety of electronics applications.

What to Watch
Drifting from pattern
Recent correlation (-74%) is running 1.1σ away from the long-run average of -41%.
Holds across regimes
Correlation is similar when markets rise (-20%) and fall (+7%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
Time Series
Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.

Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
